The Role of Transoral Robotic Surgery in the Management of HPV Negative Oropharyngeal Squamous Cell Carcinoma.

The incidence of oropharyngeal squamous cell carcinoma (OPSCC) is on the rise. This is largely due to the rapid increase in HPV positive OPSCC, which has been shown to confer a survival advantage. HPV negative OPSCC, however, has a more aggressive tumor biology and is a challenge to treat with standard current therapies. Chemoradiation has demonstrated poor locoregional control in HPV negative OPSCC, and open surgeries are associated with high morbidity. Transoral robotic surgery (TORS) has been proposed as an option to both intensify treatment and decrease surgical morbidity for patients with HPV negative OPSCC. TORS can be utilized as a primary treatment or in persistent, recurrent, or second primary OPSCC. There is emerging data showing improved functional outcomes with TORS versus open surgery or chemoradiation. Unfortunately, there have been no randomized trials comparing TORS to chemoradiation in HPV negative OPSCC. This article will review utility of TORS for HPV negative OPSCC.
